IMPROVEMENT IN CATCH-BASINS.

Specification forming part of Letters Patent N0. 208,827, dated October 8, 1R78; application tiled September 13, 1878.

To all whom it may concern Be it known that I, BERNARD KOTTMANN, of Cincinnati, Hamilton county, Ohio, have invented a new and useful Improvement in Catch-Basins, ot' which the following is a specication In the accompanying drawings, Figure 1 is a vertical section of a basin embodying 1ny improvements. The location of this section is indicated at Fig. 2. Fig. 2 is a horizontal section of the same at the line y y, Fig. 1.

A may represent an ordinary vault or cesspool; B B, drainpipes leading thereinto; C, the main discharge-pipe, communicating by branches D and E with the vault. Of these branches, the one, D, enters the vault at bottom, and has its mouth tlush with the ioor thereof, and is closed by a valve or plug, F, having a stem, G, that reaches upward to some convenient point, where it terminates in a handle, g. The other branch, E, curves downward and then upward, so as to constitute a stenchtrap, E', and thence rises through the vault-floor, so as form a stand-pipe, E", that serves as an overflow for any excessive accumulation within the vault.

A cage or grating, H, surrounding both mouths D and E, prevents the passage into either of any large body, such as a carcass, that would be liable to clog the pipe.

The valve or plugFis preferably constructed of a disk, I, and a boss, J, perforated axially for eyebolt K, secured by nut L, into whose orifice 7tthe hooked extremity of stem G engages.

I claim as new and of my inventionrIhe combination, in a cess-pool, of branched discharge-pipe C D E, ot' which one branch, D, is flush with the vault-floor, and is provided with a valve or plug, F, and the other branch rises as a stand or overow pipe, E, and is curved downward to form a stench-trap, E, both branches being inclosed iu grating H, in the manner represented.

In testimony of which invention I hereunto set my hand.
